(AP) - A rare portfolio of photographs from Marilyn Monroe’s last sitting is up for grabs to the highest bidder.

Freeman’s auction house in Philadelphia estimates the limited- edition portfolio of 10 photos, made from fashion photographer Bert Stern’s original negatives from his June 1962 assignment for Vogue, could fetch $10,000 to $15,000 when it goes on the block Sept. 10.

The photos will be on view to the public starting Sept. 6, said Aimee Pflieger, head of the century-old auction house’s photo division.

Stern, who died in June at age 83, took more than 2,500 photos of the Hollywood icon over three days at the Hotel Bel-Air in Los Angeles. The 20-by-20-inch portfolio photos are from the first day.
